Display Comparison
Both the LG G8X ThinQ and Asus ROG Phone II feature displays with an 'Infinite' (nominal) contrast ratio, typical of OLED panels. However, the ROG Phone II boasts a slightly higher peak brightness of 626 nits compared to the G8X’s 603 nits. This difference, while not massive, translates to better visibility in direct sunlight. Both phones lack high refresh rate displays, a notable omission considering their release timeframe. The ROG Phone II’s larger size (6.59 inches vs 6.4 inches) may appeal to users who prefer a more immersive viewing experience, but the G8X’s smaller form factor offers better one-handed usability.
Camera Comparison
Both phones feature capable camera systems, but detailed specifications are limited in the provided data. Both are described as having 'Photo / Video' capabilities. Without sensor size or aperture information, a direct comparison is difficult. However, given the ROG Phone II’s gaming focus, it’s likely the G8X ThinQ prioritizes image quality and versatility. The ROG Phone II’s camera is likely tuned for quick snapshots and social media sharing, while the G8X may offer more advanced features and better low-light performance. The absence of detail suggests neither phone is a standout in the camera department.
Performance
The core difference in performance lies in the chipsets. The Asus ROG Phone II utilizes the Snapdragon 855+, a slightly overclocked version of the Snapdragon 855 found in the LG G8X ThinQ. The ROG Phone II’s CPU clocks at 2.96 GHz versus the G8X’s 2.84 GHz, providing a marginal boost in processing power. While both phones share the same CPU core configuration (Octa-core with Kryo 485 cores), the 855+’s improved thermal management allows it to sustain peak performance for longer periods, crucial for demanding games. Both devices utilize the same RAM configuration, so real-world application loading times will be similar.
Battery Life
Both the LG G8X ThinQ and Asus ROG Phone II offer excellent battery life, with endurance ratings of 111 and 114 hours respectively. This suggests similar real-world usage times. However, the ROG Phone II significantly outperforms the G8X in charging speed, supporting 30W wired charging compared to the G8X’s 21W. This translates to a much faster 0-100% charge time for the ROG Phone II. The ROG Phone II also features 10W reverse wired charging (QC4), allowing it to charge other devices, a feature absent on the G8X.
Buying Guide
Buy the LG G8X ThinQ if you need a more traditionally styled smartphone with a focus on versatility and a slightly brighter display. It’s a good option for users who want a premium experience without the overtly ‘gamer’ aesthetic. Buy the Asus ROG Phone II ZS660KL if you prioritize gaming performance, faster charging, and don’t mind a larger, more specialized device. It’s the clear winner for mobile gamers and power users who demand the best possible performance.
